ice core

Ice core samples were also made, but with mixed success.

Ice cores have been taken from many locations around the world.

This was made in order to drill a high resolution ice core over the next three years.

Ice cores are also used to find out the temperature back to about half a million years ago.

Scientists study ice cores to find out how the climate was in the past.

This is a huge amount higher than at any time during the last 425,000 years, the information for which has been collected from ice cores.

Oeschger was a pioneer and leader in ice core research.

The analysis of ice cores in glaciers to understand climate change.

Ice cores show that events such as this occur approximately every 150 years on average.

During this first season, they also dug a few shallow ice cores to test out the site.

It does not apply in ice cores where the site remains frozen all year.

Evidence of this cold period is also found in dendrochronology and ice cores.

Ice cores help us know what the temperature was on the planet in the past 800 thousand years.

Ice core samples brought to the surface by drilling machines are windows into the past.

These conditions allow an ice core to form, but also provide it with a supply of artesian ground water.

Ice core data from glaciers provides insight into past climate.

An analysis of ice cores can provide information from thousands of years ago.

We have three main sources of information: written records, pollen, and ice cores.

This analysis is conceptually comparable to the study of ice cores.

Ice core samples were also collected from this region for dating purposes.

An ice core is a long piece of ice taken from a glacier.

C1 Ice cores might help predict the next ice age.

The red stars are the ice core locations and the blue line shows the route they have traversed.

He created the ice core research program at Ohio State while still a graduate student there.

Atmospheric composition data from ice core and other records could allow the record to be extended back centuries.
